SELO/SETO Electric O-type 3-way ball valve,component by 3601R series angle travel electronic electric actuators and valve body. It is divided into L-type (SPLO) and t-type  (SPTO).according to the different ball core structure. SPLO-type is used for changing flow direction of medium,Can make two perpendicular channels connected or switch direction.SPTO-type Can make three perpendicular channels connected or two of the three channels connected. Changing the relative position of pipe and core, can texecute commutation and shunt or confluence combined control of the fluid of three perpendicular pipe lines. Valve body has small port resistance and big flow coefficient, different metal and nonmetal sealing material combination can be ensured in - 29 ~ 45 temperature range, cutting conveying reliable performance excellence. SELO/SETO Pneumatic O-type 3-way ball valve with compact structure, having advantages of smooth operation, long service life
